High temperature prefabricated directly buried insulation pipe is a kind of directly buried prefabricated insulation pipe with good thermal insulation performance, safe and reliable, and low engineering cost. It can effectively deal with the heat preservation, sliding smoothness and waterproof of exposed pipe end of prefabricated directly buried insulation pipe for urban central heating at medium and high temperature. High temperature prefabricated directly buried insulation pipe not only has the advanced technology and practical performance that traditional trench and overhead laying pipeline are difficult to compare, but also has significant social and economic benefits, which is also a powerful measure of heating energy saving.

高溫預制直埋保溫管采用直埋供熱管道技術，標志著供熱管道技術開展曾經(jīng)進入了新的起點。聚氨酯直埋保溫管廣泛用于液體、氣體的輸送管網(wǎng)，化工管道保溫工程石油、化工、集中供熱熱網(wǎng)、空調通風管道、市政工程等。高溫預制直埋保溫管是一種保溫性能好，加安全可靠，工程造價低的直埋預制保溫管。有效的解決了城鎮(zhèn)集中供熱中130℃－600℃高溫輸熱用預制直埋保溫管的保溫、滑動潤滑和管端的防水問。

The technology of directly buried heat supply pipeline is adopted for high temperature prefabricated directly buried thermal insulation pipe, which indicates that the development of heat supply pipeline technology has entered a new starting point. Polyurethane directly buried insulation pipe is widely used in liquid and gas transmission network, chemical pipeline insulation engineering, petroleum, chemical, central heating network, air conditioning and ventilation pipeline, municipal engineering, etc. High temperature prefabricated directly buried insulation pipe is a kind of directly buried prefabricated insulation pipe with good thermal insulation performance, safety and reliability, and low engineering cost. It can effectively solve the problems of heat preservation, sliding lubrication and pipe end waterproof of prefabricated directly buried insulation pipe for 130 ℃ - 600 ℃ high temperature heat transmission in urban central heating.

因此大大減少了工程占地，有利于環(huán)境保護，減少土方開挖量約50%以上，減少土建砌筑和混凝土量90%。同時，保溫管施工和現(xiàn)場挖溝平行進行，只需現(xiàn)場接頭，可以縮短工期約50%以上。保溫性能好，熱損失僅為傳統(tǒng)管材的25%，長期運行可節(jié)約大量能源，顯著降低能源成本。具有很強的防水和耐腐蝕能力，不需附設管溝，可直接埋入地下或水中，施工簡便迅速，綜合造價低。在低溫條件下也具有良好的耐腐蝕和耐沖擊性，可直接埋入地下凍土。

Therefore, the land occupation of the project is greatly reduced, which is conducive to environmental protection, the amount of earthwork excavation is reduced by more than 50%, and the amount of civil masonry and concrete is reduced by 90%. At the same time, the insulation pipe construction and field trenching are carried out in parallel, and the construction period can be shortened by more than 50% with only on-site joint. The heat loss is only 25% of that of the traditional pipe material. The long-term operation can save a lot of energy and significantly reduce the energy cost. It has strong waterproof and corrosion resistance, and can be directly buried in the ground or water without pipe trench. The construction is simple and rapid, and the comprehensive cost is low. It also has good corrosion resistance and impact resistance at low temperature, and can be directly buried in the underground frozen soil.

使用壽命可達30-50年。正確的安裝和使用可使管網(wǎng)維修費用極低。可設置報警系統(tǒng)，自動檢測管網(wǎng)滲漏故障，準確指示故障位置并自動報警。直埋預制保溫管保溫鋼管又稱鋼套鋼保溫鋼管,因為超細玻璃棉的耐溫性能,因此鋼套鋼保溫鋼管主要應用于蒸汽供暖保溫.鋼套鋼玻璃棉保溫鋼管選用的玻璃棉是用獨有的離心技。

The service life can reach 30-50 years. Correct installation and use can make the maintenance cost of pipe network extremely low. Alarm system can be set to automatically detect the leakage fault of pipe network, accurately indicate the fault location and alarm automatically. Directly buried prefabricated thermal insulation pipe is also called steel jacket steel insulation steel pipe. Because of the temperature resistance of ultra-fine glass wool, steel sleeve steel insulation steel pipe is mainly used for steam heating and insulation. The glass wool used in steel sleeve steel glass wool insulation steel pipe is unique centrifugal technology.
